Cleaning device

Abstract

A cleaning tool is provided which has especial utility in the cleaning of Venetian blinds. The tool incorporates a plurality of elongated protuberances supported by manifold structure communicating with a vacuum source, the protuberances preferably taking the form of tubular support members having one or more axial rows of diametrically opposed air flow holes or openings therein and being essentially entirely wrapped or encased by an air permeable pile sleeve member. The tool of this invention effects an orderly thorough removal of dust and like particulate materials from the slats of Venetian blinds and other louvered structures.

I claim: 
     
       1. A cleaning device for removing dust and like substances from both narrow and wide Venetian blind slats, comprising manifold means communicating with a source of negative pressure and being provided on one surface thereof with a plurality of closely spaced tubular protrusions, and a plurality of closely spaced tubular cleaning members supported upon said one surface of said manifold means and communicating with the interior thereof, each of said cleaning members including a tubular support member engageable at one end thereof with selected tubular protrusions for snap fitting securement thereto, each support member being apertured to provide a plurality of small diameter openings arranged in closely spaced relation along the longitudinal axis thereof, guide means connected to the opposite end of each of said tubular support members and shaped with a rounded dome-like leading surface for guiding the cleaning members into and within the Venetian blind slats, each of said cleaning members further including an air permeable pile sleeve member of sock-like configuration embracing each of said tubular support and guide means thereon in slidable tight-fitting enveloping relation therewith, each of said sleeve members, having a surface provided by a multiplicity of soft texture, short length, upright, fine diameter, and densely arranged fibers, each of said sleeve members being apertured to provide a plurality of small diameter openings arranged in closely spaced relationship along the longitudinal axis thereof and precisely located for registration with like openings in each of said support members, whereby when negative pressure is utilized dust and like substances on the Venetian blind slats are dislodged and sucked through the openings in said sleeve members and in said support members for passage into said manifold means, said support members being selectively removable from the protrusions on said manifold means depending upon the width of the Venetian blind slat being cleaned. 
     
     
       2. A tool for the removal of particulate materials from both narrow and wide Venetian blind slats, comprising means defining a manifold communicating with a source of negative pressure, and a plurality of closely spaced tubular cleaning members communicating with the interior of said manifold means and removably supported upon the exterior thereof for selective engagement or disengagement depending upon the width of the slat being cleaned, each of said cleaning members including a tubular support provided on the circumference thereof with a plurality of rows of diametrically opposed small diameter openings arranged in closely spaced relation along the longitudinal axis of each of said support members, each of said cleaning members further including an air permeable pile sleeve member removably embracing each of said support members and being effective under action of negative pressure to dislodge particulate materials from the Venetian blind slats into and through said openings in said support members and into said manifold means, each of said pile sleeve members being provided by a multiplicity of soft texture, short length, upright, fine diameter, and densely arranged fibers.
